Overall, I like it. The infographic is a really nice touch.
I disagree with one point regarding the rental portion of the “all-cash” section. The yield looks attractive because a cash purchase exchanges the amortization benefit for immediate cash flow. I would rate this as a negative as purchasing a rental with cash can mask deficiencies with the actual rental yield where amortization is often not otherwise calculated as part of the yield. If the yield is not attractive when 100% financed, the property should not be a rental. Cash on cash and IRR are lower buying the same property cash than financing. That said, I’m all for purchasing rentals with cash, but I would then immediately refinance them.
One benefit that was not mentioned to having a mortgage, particularly in a properly established and managed LLC (consult your attorney), is that encumbering properties is a wealth preservation technique that limits loss and generally makes you a smaller target for frivolous lawsuits.
